Google is currently working on a completely new operating system called Fuchsia OS which will essentially replace Android and Chrome OS with a single operating system for both mobile devices and notebooks. Along the same lines, it was also speculated that Apple was also working on merging macOS and iOS into one seamless operating system.

Rumors regarding a merged operating system started earlier this year when Bloomberg reported that Apple will soon unveil tools for developers that will allow deploying an app for both macOS and iOS machines. Since the apps target both platforms, they’d be usable with either a touchscreen or a mouse/trackpad.

Cook further highlighted that he uses both a Mac and an iPad, and he uses them for different things. While Cook uses a Mac at work, he uses an iPad at home and while traveling. Which is why he believes that merging macOS with iOS would result in too many compromises and that might adversely affect the end user.
